Provisionally accepted- College of Plant Protection, Gansu Agricultural University, Lanzhou, Gansu Province, China
Members of the genera Gymnopus and Mycena are vital for litter decomposition in tropical and humid temperate forests. In this study, Gymnopus gansuensis, Gymnopus subsepiiconicus, and Mycena glabera, which occur in northwestern China, distinguished by their morphological features and confirmed by DNA data. Gymnopus gansuensis and Gymnopus subsepiiconicus displayed separate relationships with other species in the ITS and nLSU combined dataset utilized for the phylogeny of Gymnopus sect. Impudicae. Besides, Gymnopus gansuensis is characterized by pileus honey yellow at the center, margin pinkish buff to buff, stipe pinkish buff to fuscous, basidiospores elliptic to briolette. Gymnopus subsepiiconicus can be characterized by pileus clay buff to greyish brown at the center, margin pinkish buff to fawn, stipe dark brown to fuscous, and basidiospores elliptic. Based on the combined dataset of the ITS and TEF-1α, Mycena glabera has been detected as a separate lineage in the phylogenetic studies of Mycena Sect. Calodontes. The ecological behaviors of the new species are described with illustrations.
